Device for extracting and gathering air-conditioning hoses

Abstract

Device for extracting and collecting air conditioning hoses, has a flexible hose with a perimeter relief, rolled up as a helicoid along the same, a storage body inside which the hose is housed according to a longitudinal shaft of the same and a tractor unit, connected to the storage body, which also has an extraction and collection mechanism configured to extract and collect the hose. The extraction and collection mechanism has one or more helicoidal spindles, in contact with the perimeter relief, each one of which is configured to rotate according to a rotation shaft parallel to the longitudinal shaft, the rotation of which gives rise to a push force on the relief, which causes a linear displacement of the hose along the length of the longitudinal shaft.

The invention claimed is: 
     
       1. A device for extracting and collecting air conditioning hoses, comprising:
 a flexible hose ( 2 ), with:
 an external surface ( 3 ) with a perimeter relief ( 7 ) rolled up as a helicoid along the same, 
 an internal surface ( 4 ), 
 a rear end ( 5 ), and 
 a frontal end ( 6 ), 
 
 a storage body ( 10 ), inside which the hose ( 2 ) is housed according to a longitudinal shaft ( 11 ) of the same, having:
 a rear wall ( 12 ) with an air input ( 13 ) that connects to the rear end ( 5 ) of the hose ( 2 ); and 
 
 a tractor unit ( 20 ), which connects to the storage body ( 10 ), having:
 a frontal wall ( 21 ), which has an extraction and collection nozzle ( 22 ), and 
 extraction and collection means ( 30 ) configured to extract and collect the frontal end ( 6 ) of the hose ( 2 ) via the extraction and collection nozzle ( 22 ), 
 
 said device ( 1 ) being characterised in that the extraction and collection means ( 30 ) comprise one or more helicoidal spindles ( 31 ) in contact with the perimeter relief ( 7 ), each one of which is configured to rotate according to a rotation shaft ( 32 ) parallel to the longitudinal shaft ( 11 ), the rotation of which gives rise to a push force (F) on said relief ( 7 ), in turn resulting in the linear displacement (D) of the hose ( 2 ) along the length of the longitudinal shaft ( 11 ); 
 wherein the storage body ( 10 ) and tractor unit ( 20 ) connect via an intermediate wall ( 23 ), each one of the helicoidal spindles ( 31 ) being arranged horizontally between said intermediate wall ( 23 ) and the frontal wall ( 21 ) around the hose ( 2 ); and 
 wherein the extraction and collection means ( 30 ) comprise a plurality of driven pulleys ( 38 ) arranged on the intermediate wall ( 23 ) around the hose ( 2 ) which engage with a transmission element ( 37 ), and wherein the transmission element ( 37 ) in turn engages with the transmission end ( 33 ) of each helicoidal spindle ( 31 ). 
 
     
     
       2. Device for extracting and collecting air conditioning hoses according to  claim 1 , characterised in that it comprises four helicoidal spindles ( 31 ). 
     
     
       3. Device for extending and collecting air conditioning hoses according to  claim 1 , characterised in that each helicoidal spindle ( 31 ) comprises a transmission end ( 33 ) and a driven end ( 34 ), configured to facilitate the fastening and rotation of said helicoidal spindle ( 31 ). 
     
     
       4. Device for extracting and collecting air conditioning hoses according to  claim 1 , characterised in that the extraction and collection means ( 30 ) comprise a motor ( 35 ) that actuates a transmission pinion ( 36 ) and a transmission chain ( 37 ), which engages with a transmission pinion ( 36 ) and with the helicoidal spindles ( 31 ), in order to give rise to the rotation thereof. 
     
     
       5. Device for extracting and collecting air conditioning hoses according to  claim 1 , characterised in that it comprises a frontal support ( 40 ) with a cylindrical configuration, arranged inside the hose ( 2 ) as it passes through the tractor unit ( 20 ), configured to support the hose ( 2 ) and prevent the same from becoming deformed. 
     
     
       6. Device for extracting and collecting air conditioning hoses according to  claim 5 , characterised in that the frontal support ( 40 ) comprises one or more surface roller paths ( 41 ) in contact with the internal surface ( 4 ) of the hose ( 2 ) in order to encourage the displacement thereof. 
     
     
       7. Device for extracting and collecting air conditioning hoses according to  claim 5 , characterised in that a rear support ( 50 ) comprises a second end ( 54 ) connected to the frontal body ( 40 ). 
     
     
       8. Device for extracting and collecting air conditioning hoses according to  claim 1 , characterised in that it comprises a rear support ( 50 ) configured in a straight line, arranged inside the hose ( 2 ) as it passes through the storage body ( 10 ), configured to support the hose ( 2 ). 
     
     
       9. Device for extracting and collecting air conditioning hoses according to  claim 8 , characterised in that the rear support ( 50 ) comprises a first end ( 52 ) connected to the rear wall ( 12 ), which defines a number of openings ( 53 ) for the air to flow through via the air input ( 13 ). 
     
     
       10. Device for extracting and collecting air conditioning hoses according to  claim 8 , characterised in that the rear support ( 50 ) comprises a containment structure ( 55 ) for the hose ( 2 ) around the same. 
     
     
       11. Device for extracting and collecting air conditioning hoses according to  claim 1 ,
 wherein said transmission element ( 37 ) comprises a transmission chain ( 37 ).
